Microsoft will offer U.S. government agencies the option to host their Office 365 suites in a dedicated "cloud community" reserved only for government customers, the company said on Thursday.

The new option, whose availability date is yet to be determined, is the latest effort targeting government agencies that sign up for Office 365, the cloud-based e-mail and collaboration suite that includes online versions of Exchange, SharePoint, Office and other Microsoft applications.

Giving government agencies a variety of options is crucial because not all public sector customers have the same needs in terms of regulatory compliance, security, data privacy and product functionality, Microsoft said in a blog post.

"Today we offer our customers the choice between Office 365 public or private cloud solutions hosted in a dedicated ITAR [International Traffic in Arms Regulations] or multi-tenant environment. We're also committed to delivering an Office 365 government community cloud for our US customers," reads the post.

Asked to elaborate on the "community cloud" idea, a Microsoft spokeswoman said customers who choose that option will have their data stored in a separate, government-only environment.

"Our intent is to provide for unique government requirements such as FISMA and FedRAMP as customers require it," the spokeswoman said via e-mail.

As acceptance of the cloud increases at organizations, in particular for e-mail and collaboration software, vendors like Microsoft, Google and others are tailoring their sales pitches to the needs of specific vertical industries, such as the public sector, as well as health, finance and education.

Office 365 has a familiar look and feel, and great integration with the desktop Microsoft Office. It also offers additional tools that make it a leading choice for organizations seeking an online productivity suite. Read the full review
